Sys files are files which are used by your OS, sometimes by system application.
Windows XP is a long time operating system from Microsoft. The bootable files in that OS are command.com, autoexec.bat, win.ini, win.ini, and ntdetect.exe. There files are needed for proper booting of the OS.
Computer Os = "Computer Operating System" It contains files that are used to run a computer......
Hierarchical
Why not? If both computers share the same hardware capability (writable CD, USB port, Ethernet adapter, floppy drive) then you can use that to transfer files. Otherwise, you can always upload the files to a web server such as http://drop.io/ and then download the files on the newer computers.
All the files under C:\Windows, which is what contains the OS.
Photoshop files use the extension .psd in Mac OS X.
Re installing the Windows OS without formatting the disk will keep your files safe. Only the system files will be rewirtten no change will be to the data files. But files stored in My Documents and Desktop will be lost if you are going for a clean installation. Download Recover My Files software to recover your old files after a system crash.
Back up the files to another disk change the os and restore the files.
Structured files contain records, unstructured files are byte-streams. (Modern OS's (Windows, UNIX) have only unstructured files.)
Your OS/Operating System handles all features on your computer. The OS deals with the computers tasks from running a program to the saving of files. You cannot have a working computer without an OS.
